Continuity mistake: After the Battle of Bull Run, Jonas Steele is seen surveying the aftermath. Trouble is, there are a heck of a lot more dead bodies lying around outside the house than there were when the battle was raging, including those of Union soldiers. As the scenes of the battle demonstrated, the Union never actually got as far as the house; all their casualties were incurred on the slopes approaching the house, and then they retreated.
Other mistake: A few times during the whole show there are certain shots where the corners of the screen are blacked out, as if a circular lens cap has been fitted to the camera. There seems to be no logical reason for this, therefore it has to be a mistake. One example is when Jonas is leaving his wife for the last time and he says 'there's a big battle brewing'.
Question: When Jonas's wife descends the stairs in her nightgown, you can hear her shoe soles hitting the stairs. I was surprised to see her wearing grey stiletto high heel pumps! As she exits the stairs and enters the kitchen, these heels are fully visible on both feet from the rear. Was she that much shorter than her co-star?
